Detection of HDCD Mastered CDs
High Definition Compatible Digital (HDCD) mastered CDs deliver improved audio fidelity on any PC. HDCD has been used in the recording of more than 5,000 CD titles, including more than 225 Billboard Top 200 recordings and accounting for more than 300 million CDs sold.
搞半天還是不清楚到底WMP要怎麼提昇聲音細節,要是能輸出20Bit的數位訊號那就有搞頭。不過之前曾經在WMPXP播放HDCD時用CardDeluxe錄製輸出的數位訊號,發現跟資料與抓音軌的結果幾乎完全相同,不一樣的地方在於該軌快結束之處資料變0和開頭的offset。而用Winamp CD Reader錄到的資料就與抓音軌結果相差offset而已。或許正式版效果會不一樣吧。\r
上面提到測試的WMPXP是從WinXP試用版抽出來的,下載位置http://microke.3322.net/mp8_eng.zip,只能在Windows2000下安裝。
